AGRICULTURAL IMPLEMENT.

Specification of Letters Patent.

Patented May 19, 1919.

Application filed May 20, 1909. Serial No. 497,312.

To all whom it may concern:

Be it known that I, JACOB HERMAN, a citizen of the United States ofAmerica, residing at Braddock, in the county of Alleglieny and State ofPennsylvania, have invented certain new and useful Improvements inAgricultural Implements, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to agricultural implements of that class whichmay be termed a double plow and the object thereof is to provide anagricultural implement in the manner as hereinafter set forth andclaimed embodying a pair of plow points, each of which is independentlyadjustable of the other when occasion so requires.

A further object of the invention is to provide in a manner ashereinafter set forth an agricultural implement which will be strong anddurable as well as saving considerable time, labor, and expense, intilling the soil, particularly of large farms and ranches.

With the foregoing and other objects the invention consists of the novelconstruction, combination, and arrangement of parts as hereinafter morespecifically described and illustrated in the accompanying drawing,wherein is shown the preferred embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claims hereunto appended.

In the drawings: Figure 1 is a plan partly in section of an agriculturalimplement in accordance with this invention, Fig. 2 is a side elevationof the implement, the walls being broken away, Fig. 3 is a sectionalside elevation, Fig. 4 is a rear elevation, and Fig. 5 is a detail inperspective illustrating a hanger and a yoke forming the elements of oneof the plow elevating mechanisms.

Referring to the drawings in detail, 1 denotes an axle provided withspindles 2 on which are mounted wheels 3.

4 denotes a beam which projects forwardly from the axle 1 and which hasits outer end bent upwardly and forwardly as at 5 to a position in aplane above that of the axle 1.

Connected to the outer or forward end of the beam 4 is a depending post6 constituting what may be termed a king-bolt for truck 7 provided witha pivoted tongue 8 to which the motive or horse power is attached tomove the implement I over the soil to be tilled.

At each side of the beam 4 is arranged a longitudinally-extendingsupporting member, one of the supports being indicated by the referencecharacter 9 and the other by the reference character 10. The support 9at its forward end is secured to one side of the beam 4 and at its rearend to the axle 1. The support 10 is secured at its forward end to theside of the beam 4 and projects rearwardly over the axle 1 as well asbeing secured to said axle. The support 9 is substantially arch-shapedwhereby the central portion of said support 9 will be arranged in aplane above the beam 4. The support 10 extends in a longitudinal planewhich is substantially in parallelism with respect to the centralportion of the support 9.

The support 9 is provided with a series of vertically-disposed slotswhich are indicated as at 34, 35, and 36. Extending into the slot 34 isthe upper end of a hanger 39, the said upper end beingpivotally-connected to the support 9 by the pin 37 which extends throughthe said upper end. Projecting into the slot 35 is the upper end of ahanger 49, the said upper end being pivotally-connected to the support 9by a pin 38 which extends through the said end. The lower ends of thehangers 39 and 40 are connected together by a tie rod 41.Fivotally-connected to the hanger 39 intermediate its ends as at 42 is asuspension arm 43 and pivotally-connected to the hanger 40 intermediateits ends as at 42avis a suspension arm 44. The lower ends of thesuspension arms 43 and 44 are pivotally-connected as at 44a to plow beam45 from which depends the forward plow 46. Owing to the foregoingarrangement the plow beam 45 is suspended in such manner that it can beshifted to elevate or lower the plow 46. The means for shifting the plowbeam 45 consists of a lever 47 extending through the slot 36 of thesupport 9 and mounted up'on the pivot 47a. The lower end of the lever 47is connected by a rod 48 to a depending extension 49 of the hanger 40.

The reference character 52 denotes an operating lever which has thelower bifurcated end 51 straddling the support 9. The bifurcated end 51of the lever Y 52 is fulcrumed upon the pivot 33 of the hanger 40 and isconnected by a stirrup V to the upper end of the lever 47. The operatinglever 52 is provided with a gravity latch 53 adapti 11o i ed to engagethe keeper 54 upon the support bifurcated lower end 74 of an 9 wherebythe operating lever 52 can be held ver 75.

in position to maintain the beam 45 in its adjusted position. If theupper end of the lever 52 is swung rearwardly `the :hangers 39 and 40will be carried therewith, which in turn will move the suspension arms44 and 43 rearwardly elevating the beam 45, the latter carrying the plow46 therewith. If the lever 52 is swung in the opposite direction theplow will be moved toward the soil or deeper into the soil.

Secured to the under side of the beam 4 is a transversely-extendingbrace 55, to each end of which is attached the forward end of a tie rod56, each of said tie rods being angularly-disposed with respect to thebeam 4 and has its rear end connected to the axle l as at 57.Pivotally-mounted in the brace 55 is a rearwardly extending yoke, onearm being indicated at 58 and the other as at 59, the arm 58 beingshorter than the arm 59 and is pivotally-connected to the lower end ofthe lsuspension arm 44. The arm 59 of the yoke will be hereinafterreferred to.

rEhe support l0 is formed with a slot 60 intermediate its ends and isprovided at its rear end with an overhanging bifurcated eX- tension 6l.Extending into the slot 60 is the upper end of a hanger 68, the saidupper end of the hanger 63 being pivotally-connected to the support l0by a pin 76. Straddling the vrear end of the support l0 is a hanger 65and extending through the hanger 65 and support 10 is a pin 64 wherebythe hanger is pivotally-connected in position. Pivotallyconnected to thehanger 63 intermediate its ends as at 63a is a suspension arm 66 andpivotally-connected to the hanger 65 as at 64b is a suspension arm 67.The lower ends of the arms 66 and 67 are pivotally-connected to the plowbeam 68 as at 68a. The plow beam 68 supports the rear plow 69. The arm59 of the yoke which is carried by the brace 55 is connected to thesuspension arm 67. The support l0 is cut away as at 77 to provide aclearance for the operation of the suspension arm 66 and hanger 63.

Pivotally-connected to the lower end of the hanger 68. as at 69b is anextension 69c which projects from the forward end of a yoke 70. The yoke70 straddles the beam 68 and is pivotally-connected at a point removedfrom its rear end as at 70a to the lower end of an extension 7 Ob whichdepends from the hanger 65. The rear end of the yoke 70 is provided withan apertured lug- 70c to which is kattached the lower end of a link 7l.

Pivotally-mounted in the bifurcated eX- tension 6l as at 61a is a lever72, the lower end of which is secured to the upper end of the link 7l.Attached to the upper end of the lever 72 is the rear end of a rod 73the forward end of said rod being secured to the operating le- Thebifurcated lower end 74 of the lever 75 straddles the support l0 and ispivoted upon the pin 76. The operating lever 75 vis provided with alocking mechanism similar to the operating lever 52 as at 76a. lf thelever 75 is swung rearwardly the beam 68 will be elevated carrying theplow 69 there with, if moved forwardly the plow 69 will be shiftedtoward the soil or will be caused to penetrate deeper into the soil.

Mounted upon the beam 4 is an angularlydisposed seat post 8O providedwith a seat 79.
